ABSTRACT:
One embodiment of a temporary enclosure structure includes a rear frame section and a pair of side frame sections. The rear frame section includes a pair of spaced apart tubular vertical support members and a pair of extensible tubular horizontal members attached between the vertical support members to define a generally planar frame. Each of the side frame sections includes a pair of extensible vertical members and a pair of extensible horizontal members connected therebetween to also define a generally planar frame. Each vertical support member of the rear frame section includes a pair of spaced apart frame supports for supporting each of the side frame sections and against which the extensible horizontal members rests. Each frame support includes a rear pipe section concentrically disposed about a vertical support and a removable fastener for connecting the rear pipe section thereto. A forward pipe section, integral with the rear pipe section, is concentrically disposed about an extensible vertical member of the side frame section and is adapted to permit extension of the side frame vertical member. A second embodiment of the temporary enclosure structure includes a rear frame section and a side frame section similar to the first embodiment. The second embodiment includes an upper frame section including a pair of nested extensible tubes, each mounted to opposite vertical members of the side frame section. The temporary enclosure structure of the second embodiment is particularly adapted for use with vaulted or cathedral ceilings.
